Key Features
- Add inline protection to a coaxial CCTV connection using the device’s BNC connections.
- Limit surge exposure on the protected conductor with a 5 kA maximum discharge rating.
- Keep signal attenuation low with a specified insertion loss below 0.2 dB and a pass band up to 1 GHz.
- Fit the compact cast-aluminium body into installations where space around video equipment is limited.
- Use the dedicated ground lead to integrate the protector into the installation’s earthing arrangement.
Product Information
The MSTronic MS-T100C is an inline coaxial surge protector for CCTV signal connections. Its BNC connection arrangement suits a single video cable path, while the compact aluminium body and flexible connection lead make it practical to position near compatible camera or recording equipment. The design protects a single conductor in common mode and requires a suitable earth connection through its grounding lead.
The manufacturer’s archived exact-model datasheet specifies a 0–1 GHz pass band, less than 0.2 dB insertion loss and a response time below 5 ns. Check the electrical requirements and connectors of the CCTV system against the full table before installation. Ethernet data rates and PoE capabilities are not specified for this BNC model, and no compatibility claim is made for particular modern HD-over-coax formats.
The documented ground lead is 14 AWG with a nominal length of 275 mm. The published 80 g value is product weight, not packed shipping weight. No separate mounting kit or additional accessories are identified as included in the available datasheet.
